How could all three of them have come into existence at the same time since RNA DNA and proteins all need each other for life to continue?

RNA doesn't need proteins nor does it need DNA.
RNA probably came first. And it is known that RNA can form peptide bonds which can make proteins.
DNA would have come later.
They don't need each other, from an evolutionary standpoint. Modern DNA and RNA and proteins are interlocked, but earlier forms clearly weren't.

What proteins function to break down other proteins?
Proteases.
Proteins are broken down into proteases and peptides by proteases in?
Proteases are proteins which cleave other proteins in difference places. There may be other ways that proteins are broken down also.
Large relay proteins to which several other relay proteins are simultaneously attached?
scaffolding protein
Is proteins production part of membrane proteins?
Membrane proteins and all other proteins are produced in cytoplasm. The proteins targeted to membranes by specific signals. Golgi vesicles transport the proteins to membrane. Not all proteins are membrane proteins

Sulfur and phosphate are found in proteins and not in other macronutrient.
What is called when a cell packages proteins and other materials?
The cell that packages proteins and other things are the Golgi Apparatus.
Do proteins contain other chemical compound?
some of the proteins contain only anion acid residue ,& called simple proteins whlie many other proteins contain chemical compounds other than amino acids , thos proteins are called conjugated proteins . the non amino acid part are called prosthetic group, essential for function.
How does mRNA lead to new viral particles?
mRNA is a "message" that is transcribed into proteins. The proteins form the capsid and other proteins the virus needs. The virus also needs genetic material so it can propagate in other cells. If a virus is a + strand ssRNA (coding strand, analagous to mRNA) just that RNA could lead to a viral infection.
